How the DP/AS-Interface Link 65 Works
The DP/AS-interface link 65 links PROFIBUS-DP with the AS-interface with degree
of protection IP 65. The DP/AS-interface link 65 can be connected to any
PROFIBUS-DP master that can send parameter assignment frames with a length
of 32 bytes. To act as a connectivity device between the two bus systems, the
DP/AS-interface link has the functionality of an AS-interface master towards the
AS-interface and the functionality of a PROFIBUS-DP slave towards
PROFIBUS-DP. Up to 31 DP/AS-interface slaves can be attached to the
DP/AS-interface link. The DP/AS-interface link is therefore a modular slave with up
to 31 modules from the point of view of PROFIBUS-DP.
Parameter Assignment
Like all other components of the distributed I/O system ET 200, the
DP/AS-interface link is an integral part of STEP 7 and COM PROFIBUS. You can
display information about working with the parameter assignment software and
configuring at any time using the context-sensitive help.
